Hi Don,
Which chevy valves did you use? What is the overall length of the valve and the installed height of the springs? What springs did you use? I am trying to budget my build before I start. I am going to have Chet Herbert cams do a regrind for me. They were great to talk to on the phone. I talked to the cam grinder himself and he asked all the right questions (now this is the plymouth and not the big chrysler, is it staying in the 49, what are you going to run for carbs, what exhaust,what compression,etc.) He said that they even have cores on the shelf if mine is not salvageable. Cost is 75.00 for the regrind.
Thanks
